Further, ball retainer is fixed in the top of described grinding upper disc, and described ball stretches out the spacing hole of described ball retainer rotationally, and the arrangement mode of described spacing hole is identical with the arrangement mode of the hemispherical-shaped aperture of described grinding upper disc.
Further again, described arrangement mode is rectanglar arrangement.Can certainly be other arrangement modes.
Described upper installing hole is counterbore.This version can ensure that bolt does not contact with grinding upper disc.
Described bolt adopts turret head strand drilling bolt.Rotating nut, to the step place of connecting bolt, can ensure that the distance of each position is equal.If need to adjust initial tension of spring, the turret head strand drilling bolt of other specifications or the spring of other specifications can be replaced by.
The beneficial effects of the utility model are mainly manifested in: 1, have good uniformity, finished surface not easily produces thermal deformation; 2, machining accuracy is higher, respectively controls rotating speed, can realize different machining locus, obtain best surface processing effect and roll extrusion parameter by adjustment grinder; 3, cost is low, easy to operate.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 5, a kind of plane roll extrusion lapping device, comprises planetary gear 10 and grinding mechanism, and described grinding mechanism comprises grinding upper disc 3 and grinding lower wall 4, and described grinding upper disc 3 is distributed with the hemispherical-shaped aperture of rule arrangement, places ball 1 in described hemispherical-shaped aperture; Be processing stations between described grinding upper disc 3 and described planetary gear 10, described grinding upper disc 3 has installing hole, grinding lower wall 4 has lower installing hole, described bolt 6 is through described upper installing hole and lower installing hole, setscrew nut 8 is installed in the front end of described bolt 6, the spring 7 of the outer suit of described bolt 6 for providing grinding upper disc pretightning force, the upper end of described spring 7 contacts on described grinding upper disc, the lower end of described spring 7 contacts on described grinding lower wall, described grinding lower wall 8 connects with main shaft, and described planetary gear 10 is the planetary gear in planetary drive.
Ball retainer 2 is fixed in the top of described grinding upper disc 3, and described ball 1 stretches out the spacing hole of described ball retainer 2 rotationally, and the arrangement mode of described spacing hole is identical with the arrangement mode of the hemispherical-shaped aperture of described grinding upper disc.
Described arrangement mode is rectanglar arrangement.Can certainly be other arrangement modes.
Described upper installing hole is counterbore.This version can ensure that bolt does not contact with grinding upper disc.
Described bolt adopts turret head strand drilling bolt.Rotating nut, to the step place of connecting bolt, can ensure that the distance of each position is equal.If need to adjust initial tension of spring, the turret head strand drilling bolt of other specifications or the spring of other specifications can be replaced by.
Fig. 4 is the structure principle chart of two-sided planetary polisher lapper.Fig. 1, Fig. 2 and Fig. 3 are the roll extrusion abrasive disks of design.
With reference to figure 1, Fig. 2 and Fig. 3, roll extrusion abrasive disk comprises for grinding upper disc and grinding lower wall.Grinding upper disc 3 is distributed with the hemispherical-shaped aperture of regular array, in spherical pore, is placed with ball 1.In Fig. 2, ball arrangement mode is rectanglar arrangement, is spaced apart 40*40, abrasive disk external diameter 460mm.
Ensure ball 1 Free-rolling in spherical pore in order to fixing ball 1, above grinding upper disc 3 and ball 1, be provided with ball retainer 2.Ball retainer 2 is fixedly connected with grinding upper disc 3 hexagon socket cap head screw 5 stood upside down.
Grinding lower wall 4 is connected with main shaft.Grinding upper disc 2 is connected with nut 8 with lower wall 4 bolt 6, and both guarantees can synchronous rotary.Diameter is enclosed within bolt 6 outer ring slightly larger than the spring 7 of bolt 6, and between grinding upper disc 2 and lower wall 4.
The pretightning force of spring 7 depends on the distance between grinding upper disc 2 and lower wall 4, and rotating nut 8 can adjust the pretightning force of Distance geometry spring 7 between the two.In order to ensure that grinding upper disc 2 is in level, the pretightning force of each spring is equal, and bolt 6 adopts a kind of stepped bolt, i.e. turret head strand drilling bolt.Rotating nut 8, to the step place of bolt 6, just can ensure that the distance of each position is equal.If need to adjust initial tension of spring, the turret head strand drilling bolt of other specifications or the spring of other specifications can be replaced by.
Roll extrusion grinding implementation method is as follows:
With reference to figure 4, workpiece 11 is affixed on below planetary gear 10, and workpiece is facing to the ball 1 be distributed on grinding upper disc 3.Centre wheel 12, planetary gear 10 and internal gear 9 relative position on roll extrusion abrasive disk is arranged, as shown in Figure 5.
With reference to figure 4, to planetary gear 10 imposed load, load passes to workpiece 11, ball 1 and grinding upper disc 3 successively.Load applying, by cylinder or feed screw nut, does not do requirement to load mode here.
With reference to figure 1 and Fig. 3, grinding upper disc 3 has the trend moved downward under the effect of roll extrusion load.When load exceedes spring 7 pretightning force, grinding upper disc 3 can continue downwards along screw rod, and pretightning force also increases gradually, until balance each other with load.Spring 7 under compressive state can provide restoring force, adjusts the contact condition of ball 1 and surface of the work adaptively, ensure that steadily carrying out of processing, solves the problem that fully processing is failed to obtain in the lower surface of part of bringing because of surface of the work out-of-flatness.When grinding upper disc 2 moves downward, because bolt 6 maintains static, in order to ensure that bolt 6 does not contact with grinding upper disc 2, the position that bolt 6 coils 4 under milling sinks slightly, and has through hole at the correspondence position of grinding upper disc 3.
With reference to figure 4 and Fig. 5, the rotating speed of setting grinding lower wall, centre wheel and internal gear, machines.According to the principle of cyclic train, workpiece 11 along with planetary gear 10 together, around own axes rotation, and revolve round the sun around central axis.Ball 1 on grinding upper disc 3 roll extrusion surface of the work again and again, leaves uniform roll extrusion track from the teeth outwards.By the rotating speed of adjustment grinding lower wall, centre wheel and internal gear, various different roll extrusion track can be obtained.
